Hermle?

Well, yes, Hermle made (or still makes) these.
I had a new one a couple of years ago.

PS:
Wait a minute, they are also still being made to present by AMS,
Alois Mayer, Schönenbach.
Mayer has been in business since ca. 1840.

I had one for a few years and sure did enjoy it early in my collecting experience. Later however after selling it and having it returned a long time later and also learning a lot in the meantime enjoyed resurrecting it, I did find it worked quite fine on a pound and didn't really need the hundred pound weight.

 

Awesome.
Staiger (Werner and later Staiger Bros.) were founded in 1883 in St. Georgen
and there was a fusion with Kundo after 1992.
After the 1970s, Staiger was mainly known for their quartz clock mkovements.
The company produced a multitude of plastic parts, grips, handles and such, for
brushes and shaving brushes, not very much focussed on clocks.
The company's experience with those products helped them along, during the "quartz
revolution" and they were able to manifest themselves against domestic and Japanese
products. Seems they went down in the early 2000s from one day to another. The factory
was used as a theater for some time.
Can you show us the stamp, shimmystep?

Thanks for the pic. Yepp, it sorta fits the movement....

 

Shimmybstep,
It appears to be an early version of one that I had. It appears that Hermlee made an earlier model.

just got one of these (staiger) off of craigslist for $20... wouldn't regulate so i went through it today... we'll see.

just wanted to note the existence of another one in the wild!

 

I have one of these I thought was a Hermle till I tried to take it apart. The hands wouldn't turn. Attempting to take it apart but I cannot figure out how this center shaft comes apart. It also is bent from mine or someone's attempts to do so. Can anyone tell me how?

 

First of all, most of the time it is better not to remove these two wheels and rather try to clean with leaving them in place. If you really need to take it apart, this is how it goes: The pinion on the center arbor is a friction fit. You need something like a craw's foot to slide between the pinion and plate and then drive the arbor out, by cautiously hammering with a plastic hammer. Don't use a regular hammer or you will deform the top section of the arbor which will cause problems later on when you try to put the pinion back on. It may also cause problems when you put the minute hand on if this area is deformed. To put the pinion back on you will need a hollow punch or a piece of brass tube with a bore wide enough to let the arbor slide in.

Great advise from Uhralt. I almost never remove these. Clean in ultrasonic or use hot soapy water getting into the tight spots with a small bristle paint brush. That center arbor can be straightened in a vise or carefully using long flat-nosed pliers.

 

Thanks guys. I usually don't remove these either except that the hands wouldn't move before disassembly and I cannot see where there is a tension spring or "clutch". I assume it is somewhere between the cannon pinion and the plate but prying on it seemed to loosen something but it won't budge any further. How is the tension held for the hands?

 

Steam,
Someone had a similar problem, with a similar movement, a few months back. Was that you? I dont think the problem was resolved but I may have missed something. Willie X

 

Yeah it was me. Haven't had time to do clock work this summer. I got the hands to move by gently pulling the hands outward but time keeping was erratic. When I pulled it apart this morning I found the was arbor bent. I know this is causing my regulation issue but I can't understand how the tension is maintained on the hands.

 

Well it took a little patience but I finally got this apart. The cannon pinion is mounted on a pipe that is either pinched or staked over the arbor. Nothing inside so I still am perplexed by how tension is maintained for the hands. Evidently someone had an accident with this thing resulting in the pipe and the arbor being bent. the arbor I can straighten, the pipe a little harder. Am I missing a part ?

 

Well, there has to be a disconnect (clutch) between the center-shaft and the minute hand. What is the minute hand attached to and exactly how is the minute hand attached? Keep those photos coming.

Maybe someone has one of these. That deep and wide groove in the center shaft looks suspicious.

The pipe should be a light friction fit on the arbor. The arbor is very slightly conical, so the deeper the pipe is pushed on the arbor, the more friction there is. This is in lieu of a clutch and allows the minute hand to be set. Most French clocks are similar in design. When there is insufficient friction, the hand will slip, when there is too much tension, it will be hard to turn the minute hand manually. The dent on the pipe is probably somebody's attempt to increase friction.

Uhralt

 

To straighten the pipe, you could insert a fitting smooth broach from the back. This will prevent the pipe to collapse while trying to straighten it. The broach will get stuck where the bend begins. Keep manually bending the pipe back and keep moving the broach deeper inside. Do this until the broach clears the whole pipe without much resistance. That should bring you close.

Uhralt

 

I see the center shaft but the minute hand cannon is a mystery so far, unless I'm missing something. Generally the taper is not the source of the friction by itself but simply the carrier for the cannon which has a metal upset somewhere around the mid point to actually cause the friction.

Thanks for your observations, I tried what Uhralt suggested and the pipe seems straight now. I measured the arbor and the only taper is at the end for 1/16 of an inch and then the rest of the arbor is the same size except where it's cut out. Where the stake/crimp mark is on the pipe matches the cut out on the arbor so I'm pretty sure this is what holds it on. (there is a mark on each side)
Above these there is also some rivets? or spots that also have created some wear on the arbor and maybe this is what creates the friction. The minute hand just bolts to the end and that portion appears to be solid.

 

Thanks for the pictures. This is a rather uncommon design. Now that the pipe is straightened, do you have some friction?

Uhralt

 

Going to clan it first. Lot of nasty came out of the pipe. I'll post it when done.

 

So that smaller silver shaft turns around backwards (from the picture) and inserts into a hole bored in the end of the black center shaft?? It's not (at least to me) clear exactly what the minute hand is attached to??

If you could just lay the parts out in the open, in the manner they normally go together, it would help a lot.

WIllie X

 

Yes your right. The minute hand goes on the end of the black shaft on the fourth pic. I'll post more pics tomorrow. Thanks!
